"If you try it on I shoot!" she exclaimed. "You know what that means, Cecil. A pistol isn't a plaything with me."

Cecil looked no more toward the door. He came instead a little farther into the room.

"My dear Kate," he said, "we are willing to admit, Forrest and I, that we are beaten. You can do exactly what you like with us except leave us here. Our little joke with Engleton is at an end. Perhaps we carried it too far. If so, we must face the penalty. Take him away if you like. Personally I do not find this place attractive."

Kate lowered her revolver and turned to Engleton.

"Come over to my side," she said. "We are going to leave this place."

Engleton staggered towards her. He had always been thin, but he seemed to have lost more flesh in the last few days.

"For God's sake let's get out!" he said. "If I don't breathe some fresh air soon, it will be the end of me."

"In any order you please," Cecil de la Borne said smiling. "The only condition I make is that before you leave the place altogether, Kate, I have a few minutes' conversation with you. You can hold your pistol to my temple, if you like, while I talk, but there are a few things I must say."

"Afterwards, then," she answered. "We are going first out of the place. We shall turn seawards and wait for you. When you have come out, you will hand us your electric torches and go on in front."

"You are quite a strategist," Forrest remarked grimly. "Do as she says, Cecil. The sooner we are out of this, the better."
